Application filed J'uly,7, 1899- Serial No. 723,028. (No model.)

To all whom it may concern.-

Be it known that I, JOHN H. LAWSON, a

citizen ofthe United States, and a resident of Delaware, in the county of Delaware and,

State of'Ohio, have invented a new and useful Improvement in Horse-Rakes, which improvement is fully set forth in the following specificatlon and accompanying drawings, in which- Figu re. 1 is 'a top plan view of myimproved horse-rake. Fig. 2 is a vertical section on line X X of Fig.1. Figs. 3, 4, and 5 are detail views. v

My invention pertains to certain improvements in horse-rakes; and my object is to provide a novel and useful device combining strength and durability in construction'with facility and completeness in operation.

The peculiar features and prominent advantages of the invention will be obvious by referring to the accompanying drawings, in

V which A represents the axle, united to the lower ends of the depending bars 7.

front cross-bar 2 by convergent side bars 3, which are also connected at suitable intervals by transverse bars 4 and 5. A verticallywin'ging frame is com posed of two horizontal ars 6 and depending bars 7 which are rigidly united at their junction and reinforced by diagonal braces 8. The forward extensions of the frame are pivoted in clips 9, attached to the front cross-bar. The depending bars 7 are connected near their upper ends by iron bars 9.

A rake-head 10, provided with horizontallydisposed teeth ll, has two encircling grooves, forming bearings which are journaled in the The outer shoulders of each groove are provided with metal collars 12, having apertures to admit't'he lower ends of.plungers 13, which slide in grooves formed in the outer the depending bars. The said plungers are normally held in engagement with the rakehead by downwardly-bearing springs 14:. It.

will be understood that when the rake is in operation it cannot accidentally revolve, and

thereby prematurely dump its load.

7 A rock-shaft 15, journaled in bearings attached to the top of theaxle, carries a short arm 16 and two longer arms 17, provided at their outerends with antifriction-rollers, which engage two curved double levers 18,

sides of pivotally attached to the outer sides of the bars 61 The shorter arms of these levers are connected by rods 19. to angle-levers 20, which operate the plungers 13. A lockinglever 21 is connected by a rod 22 to the short arm 16 of the rock-shaft;

When in operation, the rake-head is locked and the teeth held in working position by the plungers. On arrival at the desired dumping-place the lever 21 is thrust forward, the action of the levers 17 and 18 raises the swinging frame, and the angle-levers 2O simu1taneously lift the plung'ers l3, releasing the rakehead. The teeth being thus free to revolve are tripped and the load is dumped. The spurs 23 successively engage the surface of the ground, and the teeth being thus restored to their operative position the rake-head is relocked by the plungers 13. 1 If it is desired to raise the rake, as shown in Fig. 3, either with the load on the rake or in traveling along a road, the pawl 24 is thrown into engagement with the lever 18, when the swinging frame will be raised by operating the hand-lever without releasing the catch 13.

' What I claim as new isi 1. In a horse-rake, the combination with the main frame and axle, a vertically-swinging frame 6 having depending rear arms 7 provided with guideways, and plungers 13 working in said guideways, of a revolving rake-head 10 provided with recesses adapted to receive the lowerv ends of said plungers, fulcrumed bell-cranks having pivotal connections with the upper ends of said plungers, fulcru med lifting-levers 18 having their upper arms jointedly connected with said bell-cranks and their lower rearwardly and downwardly extending arms contacting with the depending arms of said swinging frame, a pivoted operating-1ever and means connected with the latter for exerting a lifting pressure on the under sides of the rearwardlycurved lower arms of the levers 18, substantially as specified.

'2. In a horse-rake, the combination with the main frame and axle, of the verticallyswinging frame 6 having depending bars 7, a revoluble rake-head journaled in the lower ends of said depending bars, plunger-s 13 adapted to work in guides in said depending bars and to have their lower ends engage resaid plungers, angularlevers-lS fulcrumed to the upper arms of the frame 6, the lower rearwardly and downwardly extending curved arms of said levers 18 having contact with the depending bars 7 and a jointed connection with the bell-crank lever 20, an operatinglever 21 pivoted to the framew0rk,a journaled rock-shaft 15, an arm 16 extending therefrom, a jointed connection between said arm 16 and operating-lever, arms 17 carried on said rockshaft and adapted to engage the curved for- Ward surfaces of the lower arms of the levers 18, substantially as specified.
